Follicular growth and corpus luteum function in women with unexplained infertility, monitored by ultrasonography and measurement of daily salivary progesterone
Ovarian function was evaluated over a minimum of 3 consecutive menstrual cycles from each of 41 women with unexplained infertility. Follicular development and ovulation were monitored using real time ultrasonography and luteal function was evaluated by daily salivary progesterone measurement. In 129 spontaneous cycles, normal single ovulations were detected in 121 (93.8%). Luteal phase insufficiency was identified in 21 (17.4%) of these 121 cycles and this was a recurrent phenomenon in the cycles of 5 of the 41 women (12.2%). A successful pregnancy was seen only in association with consistently normal salivary progesterone profiles or where the empirical use of clomiphene citrate therapy had corrected previously diagnosed luteal phase insufficiency. Basal body temperature records or mid-luteal serum progesterone measurements were less satisfactory indices of luteal function than a salivary progesterone profile.

Insulin resistance (IR) plays a pivotal role in PCOS. Insulin-sensitizer agents such as metformin and inositols have been shown to improve the endocrine and metabolic aspects of PCOS. The purpose of this study is to compare their effects on the clinical and metabolic features of the women with PCOS. Fifty PCOS women with IR and/or hyperinsulinemia were randomized to treatment with metformin (1500 mg/day) or myo-inositol (4 g/day). IR was defined as HOMA-IR >2.5, while hyperinsulinemia was defined as a value of AUC for insulin after a glucose load over the cutoff of our laboratory obtained in normal women. The Matsusa Index has been calculated. The women have been evaluated for insulin secretion, BMI, menstrual cycle length, acne and hirsutism, at baseline and after 6 months of therapy. The results obtained in both groups were similar. The insulin sensitivity improved in both treatment groups. The BMI significantly decreased and the menstrual cycle was normalized in about 50% of the women. No significant changes in acne and hirsutism were observed. The two insulin-sensitizers, metformin and myo-inositol, show to be useful in PCOS women in lowering BMI and ameliorating insulin sensitivity, and improving menstrual cycle without significant differences between the two treatments.
Thyroid autoimmunity with normal thyroid function is associated with recurrent miscarriage (RM), but the association with live birth is less clear. Therefore, we determined the association between thyroid peroxidase antibodies (TPO-Ab) and live-birth rate (LBR) in a retrospective cohort of euthyroid women with unexplained RM. We included 202 women of which 28 were TPO-Ab positive (13.9%) and 174 were TPO-Ab negative. TPO-Ab positive women (n = 10) without levothyroxine treatment had a lower LBR (29%) compared to TPO-Ab negative women (51%) (HR 0.23, 0.07-0.72, p = 0.012). The LBR in women with TPO-Ab receiving levothyroxine was not different compared women without TPO-Ab (60% versus 51%, p = 0.50). In conclusion, TPO-Ab are associated with a lower LBR in euthyroid women with unexplained RM and these women may benefit from treatment with levothyroxine.
A controlled trial recently showed that oral micronized progesterone (Progesterone, 300 mg at h.s. daily) was effective for vasomotor symptoms (VMS) in 133 healthy early postmenopausal women. Here, we present subgroup data in women with severe VMS (50 VMS of moderate-severe intensity/wk) and also 1-mo withdrawal study outcomes. Women with severe VMS (n = 46) resembled the full cohort but experienced 10 VMS/d of 3 of 4 intensity. On therapy, the progesterone VMS number (#) decreased significantly more than placebo # to 5.5/day (d) versus 8/d (ANCOVA -2.0 95% CI: -3.5 to -0.4). Just after trial mid-point, a withdrawal substudy (D/C) was added--56 women were invited and 34 (61%) took part (progesterone 17; placebo 17). Those in the D/C cohort resembled the whole cohort. On stopping, VMS gradually increased--at D/C week 4, on progesterone, VMS daily # reached 78% and significantly less than baseline (-3.0 to -0.8) but placebo VMS # did not differ from run-in. In summary, progesterone is effective for severe VMS and does not cause a rebound increase in VMS when stopped. That progesterone may be used alone for severe VMS and unlike estrogen does not appear to cause a withdrawal rebound increases VMS treatment options.
Women with polycystic ovary syndrome (PCOS) are considered to be at increased risk of miscarriage. Since metformin has beneficial effects on the risk factors contributing to first-trimester abortion in PCOS patients, we hypothesized that metformin - owing to its metabolic, endocrine, vascular and anti-inflammatory effects - may reduce the incidence of first-trimester abortion in PCOS women. A prospective cohort study was set up to determine the beneficial effects of metformin on PCOS patients during pregnancy. Two hundred non-diabetic PCOS patients were evaluated while undergoing assisted reproduction. One hundred and twenty patients became pregnant while taking metformin, and continued taking metformin at a dose of 1000-2000 mg daily throughout pregnancy. Eighty women who discontinued metformin use at the time of conception or during pregnancy comprised the control group. Both groups were similar with respect to all background characteristics (age, body mass index, waist/hip ratio, follicle-stimulating hormone, luteinizing hormone, estradiol and dehydroepiandrosterone sulfate levels). Rates of early pregnancy loss in the metformin group were 11.6% compared with 36.3% in the control group (p < 0.0001; odds ratio = 0.23, 95% confidence interval 0.11-0.42). Administration of metformin throughout pregnancy to women with PCOS was associated with a marked and significant reduction in the rate of early pregnancy loss.
